In Vitro | HM30181 is shown to be approximately equipotent with the reference Pgp inhibitor tariquidar in inhibiting rhodamine 123 efflux from CCRF-CEM T cells (IC50, tariquidar: 8.2±2.0 nM, HM30181: 13.1±2.3 nM) [1]. HM30181 shows a high selectivity for mP-gp and its potency is 20-50 times higher than that of tariquitar, another third generation P-gp inhibitor[2]. |
In Vivo | PET scans with the Pgp substrate (R)-[11C]verapamil in FVB wild-type mice pretreated i.v. with HM30181 (10 or 21 mg/kg) failes to show significant increases in (R)-[11C]verapamil brain uptake compared with vehicle treated animals[1]. HM30181 inhibits P-gp mainly in the intestinal endothelium, which can be beneficial because pan-inhibition of P-gp, particularly in the brain, could lead to detrimental adverse events. HM30181 increases the oral bioavailability of co-administered paclitaxel by more than 12 times in rats[2]. |
Animal Admin | Mice: HM30181 mesylate is dissolved in 5% aqueous glucose solution, containing 20 μL 0.01 M aq. HCl and injected at a volume of 4 mL/kg. Female FVB wild-type mice, aged 8-12 weeks weighing 24±4 g undergo (R)-[11C]verapamil PET scans without and with i.v. pretreatment with cold HM30181. Animals are assigned to 5 groups (n=4 per group). One group is pretreated with HM30181 vehicle solution (5% aq. glucose solution containing 20 μL 0.01 M aq. HCl) at 60 min before start of the PET scan. The other groups are pretreated with either 10 mg/kg HM30181 at 10, 60 or 120 min before PET or with 21 mg/kg HM30181 at 10 min before PET[1]. |
